Part details
Part number: THQL1120DFS
Current rating: 20 A
Poles: 1
Voltage rating: 120 V

What it does

This GE circuit breaker automatically interrupts current if a fault or overload occurs on a single circuit. With a thermal-magnetic trip mechanism, it responds to sustained overloads and short circuits, helping prevent overheated wires and potential fire hazards. When paired with appropriate wiring (commonly 12 AWG for a 20A circuit), it provides reliable, fast protection for lights, outlets, and small-appliance circuits.

Key benefits and features

• 20 Amp, 1-Pole design—protects a single branch circuit from overload and short circuits.
• 120 V operation—suitable for standard residential lighting and outlet circuits.
• THQL-series compatibility—designed for GE load centers that accept THQL-type breakers, offering straightforward replacement or upgrade in compatible panels.
• Thermal-magnetic trip—delivers reliable protection by reacting to both overloads and short circuits, enhancing circuit safety.
• Authentic GE part—actual part THQL1120DFS ensures proper fit, connection, and performance in your GE panel.

Ideal use cases

• Replacing a blown or faulty 20A breaker in GE residential panels.
• Adding or reconfiguring a circuit for lighting, receptacles, or a dedicated small-appliance circuit that requires 20 amps.
• Upgrading panel protection with a reliable, single-pole GE breaker designed for standard 120V circuits.

Installation and care tips

• Power down the main breaker and verify there is no voltage on the panel before installation.
• Ensure the panel is compatible with THQL-type breakers and that the slot is clean and free of debris.
• Insert firmly onto the bus and snap into place until it seats securely; follow the panel manufacturer’s torque specifications for termination and mounting.
• Use the correct conductor size (typically 12 AWG for a 20A circuit) and route wires neatly to maintain safe, code-compliant wiring.
• If in doubt, consult a licensed electrician to confirm panel compatibility and safe installation practices.

Choose the General Electric THQL1120DFS for a precise, authentic replacement that maintains the safety and reliability of your GE electrical system. It’s the practical, straightforward solution for single-circuit protection in 120V residential applications.
